Epsilon naught is an equation.
Epsilon naught means that the derivative of phi at x equals zero. Other names for epsilon naught include delta squared or zeta minus “x”. The symbol ѵ was chosen to represent epsilon-naught by John von Neumann, who used it as a control variable in his work on self-reproducing automata and cellular structures.
